This thing is driving me crazy. Just got the tail sorted out it was kicking, that problem was the gains in the Ice 50. Now I changed the cyclic response from high to increased to slightly increased trying to get to the cyclic feeling I like. Now when I spool it up the swash tilts to the left just as it gets light on its skids. Went back to the high setting now it tilts to the right WTF

I checked the swash sensor direction (setup M) it is ok. Piro (setup N) is ok.

Not super familiar with Align helis but my Blade 300X does similar things due to very high frequency vibrations from the motor. How are your vibrations?

I just found my one way bearing is bad, I wonder if that was the cause.

As Utahbmxer says, this is vibration related.

Take off the main rotor blades and spool up. You want the swash to stay level. High frequency vibrations seem to be the main culprit--like the motor, or anything to do with the tail.

Also if you used the stock foam to hold the fbl controller down, try 3M4011 tape instead. It seems to work better at isolating the unit from the high frequency vibrations.

so far on my Blade 450's when the cyclic starts to tilt as its about to lift off, the problem has been the tail rotor hub. Vibration in the tail can and will lead to cyclic tilting. I have found the Blade tail rotor hubs can become slightly bent just from flying and particularly if you get a hard tail wag. You need not crash to get a bent tail hub. Not sure if the Align 450's as as sensitive. I do not have this problem with my TREX 550.

Too Tight tail blades will also cause this. Causes the vibration causing the Beast to provide cyclic input. The 3M mounting tape will also help but you are better off relying on a "best setup".

I put it on my trex 500 and terms the flybar simulator up to high when I put it back to normal it quit doing it.
